Abstract :
New vertical-cavity surface-emitting laser (VCSEL) modules-designed with a optical output rod surrounded by cladding-have been proposed to realize high-efficiency low-cost optical interconnection. Prototypes have been fabricated using a photomask transfer method employing two kinds of ultraviolet curable resin. Observation of the near-field pattern and eye pattern for signal transmission shows that output rods with a diameter of 50-mum efficiently confine the laser beam as an optical waveguide. In addition, ray tracing simulation indicates that this new VCSEL offers greater positional tolerance-as much as +18/ -22 mum-for coupling to optical wiring in 90deg light path conversion.
